Abstract

Cabinet hinge having two hinge links pivotingly attached to a door-related member on the one hand and to a wall-related member on the other, in the manner of a quadruple knuckle joint, wherein in the space between the hinge links, a resiliently deformable damping means is disposed such that, upon a swinging of the hinge into the open position, it is deformed while resting against at least one of the hinge links shortly before reaching the designated end position.

Claims

1. A cabinet hinge movable from an open to a closed position and vice versa and having an inner and an outer hinge link each pivotingly attached to a door-related member on the one hand and to a wall-related member on the other, in the manner of a quadruple knuckle joint, said hinge links being spaced from each other, said supporting wall-related member being constructed as an elongated supporting arm, an over-center mechanism formed by a pusher, a spring biasing said pusher, a projection on the supporting arm end of said outer hinge link and engaged by said pusher, said pusher, upon a swing from the closed to the open position, urging the outer hinge link first in the closing direction up to a dead center position and, on the other side of the dead center position, urging it in the opening direction, resiliently deformable damping means disposed in the space between said hinge links, said damping means being a resiliently flexible arm projecting from the pusher into the area between the hinge links, which damping means, when the open position is approached, engages the side of the inner hinge link facing the outer hinge link and flexes resiliently upon further opening movement.

2. A hinge according to claim 1, comprising a pivot connecting said outer link to said supporting arm, and wherein an abutment section is provided at the free end of the resiliently bendable arm, said abutment section being bent back to the supporting-arm-side pivot of the outer hinge link, the length of said abutment section being such that, in the predetermined open position, it engages said pivot connecting the outer hinge link pivotingly to the supporting arm.

3. A hinge according to claim 2, wherein said pusher and bendable arm are injection molded integrally from plastic.

4. A hinge according to claim 2, wherein said pusher, bendable arm and abutment section are injection molded integrally from plastic.

5. A hinge according to claim 1, comprising a pivot connecting said outer link to said supporting arm and having a bearing eye fitted to said pivot, and wherein an abutment section is provided at the free end of the resiliently flexible arm, said abutment section being bent back to the supporting-arm-side pivot of the outer hinge link, the length of said abutment section being such that, in the predetermined open position, it engages said bearing eye.

6. A hinge according to claim 5, wherein said pusher and bendable arm are injection molded integrally from plastic.

7. A hinge according to claim 5, wherein said pusher, bendable arm and abutment section are injection molded intetrally from plastic.
